NACOGDOCHES, Texas - The Audio Engineering Society at Stephen F. Austin State University will present a free screening of "Thunder Soul," a documentary about bandleader Conrad "Prof" Johnson and the Kashmere High School Stage Band, at 2 p.m. Friday, May 6, in Cole Concert Hall on the SFA campus.

Produced by Jamie Foxx and directed by Mark Landsman, the film tells the story of alumni from Houston's storied Kashmere High School Stage Band who return home after 35 years to play a tribute concert for their beloved bandleader who turned the struggling jazz band into a world-class funk powerhouse in the early 1970s, according to the IMDb description.

Now, years later, Johnson's students prepare to pay tribute to the man - age 92 at the time the film was made - who changed their lives. Some haven't played their horns in decades, yet they dust off their instruments, determined to retake the stage to show Prof and the world that they've still got it with the making of a CD release, "528-0728."

The film is one hour, 23 minutes and is rated PG for language and momentary smoking. A question-answer session will follow.
